Comparing:
E950: Acesulfame Potassium (Ace-K / 200x Sweetener)
E951: Aspartame (Dipeptide Sweetener / 200x)
E950 (Acesulfame K / Ace-K) is a calorie-free, heat-stable synthetic potassium salt sweetener approximately 200 times sweeter than sucrose. INS 950, ADI is 9 mg/kg bw/day, famous for blending with sucralose and aspartame to produce sugar-identical taste curves.
E951 (Aspartame) is a methyl ester of the aspartic acid/phenylalanine dipeptide yielding ~200x the sweetness of sucrose. INS 951, ADI is 40 mg/kg bw/day, the historic sweetener in Diet Coke and tabletop sweetener packets.
